Application filed December cloth so that as soon as the burner gets hot the heat is quickly conducted to the-brass piping and thisnmterially helps the oil to get hot in the tank and forms a gas pressure to the burner whereby the operator does not have the trouble to pump up as often as before, the iron pipes readily cool off as it is wellknown in this art. 7

It has for a further object to provide means for protecting the burner being smoked up with grease or soot. This I term the oil grease consuming plate.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims. I

The invention, in its preferred form, is clearly illustrated in the accompanying drawings, which, with the numerals ofreference marked thereon, form a part of this specification, and in which:-

Fig. 1 is a top plan view of my improved blow-torch.

Fig. 2 is a side elevation'of the same.

Fig. 3 is a longitudinal vertical section on the line 3-3 of Fig. 1.

Fig. 4 is a vertical section on line 4t of Fig. 2.

Fig. 5 is a vertical cross-section on the line 5-5 of Fig. 2.

Like numeralsof reference indicate like parts throughout the several views.

. Referring to the drawings: 1 designates a tank of any well-known approved form of construction, shape and size, as best adapted for the purpose and use to which the burner is to be put.

Rising from the tank is thepipe 2, the lower end of which is retained therein in any suitable manner, and upon this pipe is detachably mounted or otherwise retained,

.the drip cup 3. In this instance, the drip cup is shownas provided with the upwardly extending boss 4, into which is detachably screwed the tubular member 5 on which is mounted the burner body supporting mem- 7, 192?. Serial No.

her 6. This member 6 is shown in vertical section in Fig. 4." It is provided with the externally threaded extension '7 which re ceives the threaded cap nut 8, through which the valve stem 9 is suitably attached. The valve-stem is provided with a suitable handle or wheel 10 as seen in 1, 2 and '3,

which wheel or handle may be of any approved or well-known construction.

The valve is threaded as seen at 1'1,

passing loosely through the bore 12 of the Y member 6 and having threaded engagement as at 13 with threads in theboreof the meme the pointed end 16 of the valve stem is rc-' ceived w thin the tapered opening 17 of the said plug, al1 as clearly seen in Fig.

T he burner tube 18 has detachable threat.- ed engagement as at 19 with the'inncr end of the member 6, a suitable packing orv washer 20 being interposed between the inner end of the burner tube 13 and the adjacent face of the member 6, all as clearly seen in Fig. 3. The burner tube 18 is provided with radial openings 21 as seen in Fig. 3, as well as in Figs. 1 and 2, and is also longitudinally corrugated as seen at 22 in Figs. 1 and 2. This burner tube may be made of any suitable material and of any desired length and diameter.

Mounted upon the member 18 is a member 23, secured tothe upper face of the barrel by the screw 24 see Fig. 3, and this member 23 has an offset as at 25 in which is seated the member 26 which. bears upon the top of the reducedportion oft-he member 23, and extends over the band or clip 27 which is of the member 23, which clamp or band embraces-the burner tube 18 as shown, the lower ends being brought into parallel ends as will be readily understood with reference to Fig. 2, and these parallel ends 29 are held together in clamping position about the burner tube 18 by suitable bolts 30gand nut 31as seen in Fig. 2.

Mounted upon the upper face of the member 23 and disposed above the longitudinal member 26 is the member 32, the upperend of which is forked as at 33, while resting upon this member 32 at the other end is the angles to its length, as seen at 87 and upon" in the member 35 in the usual manner. The screw 24 passes through the overlapped portions of the members 32 and 34, as seen clearly in Figs. 2 and 8.

The member 26 is loosely mounted upon the screw 36 so as to be turned upon the same as a pivot to be moved from side to side, its outer end being turned at substantially right this portion 37 is detachably mounted the horizontally disposed cup-shaped member 38 retained in position thereon by suitable screw 39 andthumbmut 40, so it may be readily re moved when desired.

This forms a safety-combustion guard and constitutes a preventor against igniting nearby articles and hence as a lire protector. It is also a protection against wind when the burner is in use. As seen in 3, it ispr'ovided with a slanting curved rim 41 to catch the unburned oil when the torch is put into operation and to keep the flame from igniting the oil in the drip-cup.

As shown in Fig. 4,the member 6 is formed with multiple passages 42, 43, 44, 45 and In these passages is located brass wire cloth or the like 47, which may or may not be twisted, but preferably the latter as shown in Fig. 4. These passages are closed at their outer ends by plugs 48, preferably screw-threaded as seen in Fig. 4. One or these, 48, which is disposed in alignment with the passage 52, is adjustable.

These passages are in communication through a passage49 with the chamber 50 within the member 6, which in turn is in communication with the pipe 2, as seen in Fig. 4, by means of the passage 51, while another passage 52 atl'ords communication with the bore 14 as seen in Figs. 3 and 4., The outlet of this passage into the burner tube is controlled by the valve 16.

This particular construction of the memher 6 serves to consume the gum from the oil and enforce a stronger clear stream of gas to the outlet of the burner, and produces a very strong gas generation burner by reason of obtaining a much greater and stronge heat in the burner tube.

In some instances I may employ a gauze or analogous filter 53 in the pipe 2 as seen in Fig. 5, for obvious purpose.

The handle or wheel 10 may be of wood or u have a suitable protector in case the same 'should exceedingly hot.

lvlodihcations in detail may be resorted. to without departing from the spirit of the invention or sacrificingany of itsadvantages.

What is claimed as new is i p 1. In a blow torch, a burner tube, a sup porting member therefor, said member being lrmed with a bore and a lateral passage therefrom, and multiple passages intersecting each other and opening through the walls of said member, said member having an interior chamber in communication with an oil :l'eed pipe and with said passages.

A structure inaccordance with claim 1 in which said passages have therein a filtering material."

3. A structure in accordance with claim 1 in which is included a reticulated medium in said passages, and independent removable closures for said passages permitting ready access to the interior thereof.

In testimony whereof I afiix my signature.
